Required gcc version for KDE ? (is gcc 4.1 out ?)

[Alexander Neundorf]

Hi,

which version of gcc is required for building KDE ?
It seems gcc 4.1 doesn't work, at least currently, see the mail below.
Qt seems to require gcc 4.2 
(http://doc.qt.nokia.com/4.6/supported-platforms.html)

If so, should we add a check whether gcc is at least 4.2 and fail otherwise ?
